| 227-0102-00L | Diskrete Ereignissysteme  | 6 KP | 4G | L. Thiele, L. Vanbever, R. Wattenhofer | |
| Kurzbeschreibung | Einführung in Diskrete Ereignissysteme (DES). Zuerst studieren wir populäre Modelle für DES. Im zweiten Teil analysieren wir DES, aus einer Average-Case und einer Worst-Case Sicht. Stichworte: Automaten und Sprachen, Spezifikationsmodelle, Stochastische DES, Worst-Case Ereignissysteme, Verifikation, Netzwerkalgebra. | ||||
| Lernziel | Over the past few decades the rapid evolution of computing, communication, and information technologies has brought about the proliferation of new dynamic systems. A significant part of activity in these systems is governed by operational rules designed by humans. The dynamics of these systems are characterized by asynchronous occurrences of discrete events, some controlled (e.g. hitting a keyboard key, sending a message), some not (e.g. spontaneous failure, packet loss). The mathematical arsenal centered around differential equations that has been employed in systems engineering to model and study processes governed by the laws of nature is often inadequate or inappropriate for discrete event systems. The challenge is to develop new modeling frameworks, analysis techniques, design tools, testing methods, and optimization processes for this new generation of systems. In this lecture we give an introduction to discrete event systems. We start out the course by studying popular models of discrete event systems, such as automata and Petri nets. In the second part of the course we analyze discrete event systems. We first examine discrete event systems from an average-case perspective: we model discrete events as stochastic processes, and then apply Markov chains and queuing theory for an understanding of the typical behavior of a system. In the last part of the course we analyze discrete event systems from a worst-case perspective using the theory of online algorithms and adversarial queuing. | ||||

| Kurzbeschreibung | In this seminar participating students present and discuss recent research papers in the area of distributed computing. The seminar consists of algorithmic as well as systems papers in distributed computing theory, peer-to-peer computing, ad hoc and sensor networking, or multi-core computing. | ||||
| Lernziel | In the last two decades, we have experienced an unprecedented growth in the area of distributed systems and networks; distributed computing now encompasses many of the activities occurring in today's computer and communications world. This course introduces the basics of distributed computing, highlighting common themes and techniques. We study the fundamental issues underlying the design of distributed systems: communication, coordination, synchronization, uncertainty. We explore essential algorithmic ideas and lower bound techniques. In this seminar, students present the latest work in this domain. Seminar language: English | ||||

| 252-0213-00L | Verteilte Systeme | 8 KP | 6G + 1A | F. Mattern, R. Wattenhofer | |
| Kurzbeschreibung | Verteilte Kontrollalgorithmen (wechselseitiger Ausschluss, logische Uhren), Kommunikationsmodelle (RPC, synchrone/asynchrone Kommunikation, Broadcast, Ereignisse, Tupelräume), Middleware, Service- und Ressourcen-orientierte Architekturen (SOAP, REST), Sicherheit, Fehlertoleranz (Modelle, Consensus), Replikation (Primary Copy, 2PC, 3PC, Quorum-Systeme), Shared Memory (Spin Locks, Concurrency). | ||||
| Lernziel | Kennenlernen von wesentlichen Technologien und Architekturen verteilter Systeme. | ||||
| Inhalt | Wir geben eine Einführung in verteilte Systeme (Charakteristika und Konzepte) und diskutieren sodann verteilte Kontrollalgorithmen (Flooding-Verfahren, wechselseitiger Ausschluss, logische Uhren), Basis-Kommunikationsmodelle (Remote-Procedure-Call, Client-Server-Strukturen, synchrone und asynchrone Kommunikation), abstraktere Kommunikationsprinzipien (Broadcast, Ereignisse, Tupelräume), Namensverwaltung, Middleware und Techniken offener Systeme (z.B. REST, SOAP), Infrastruktur für spontan vernetzte Systeme (JINI), Cloud-Computing sowie Sicherheits- und Schutzmechanismen. Da partielle Systemausfälle charakteristisch für verteilte Systeme sind, werden auch Fehlermodelle und Fehlertoleranz-Algorithmen zum systematischen Umgang mit Fehlersituationen besprochen. Wir diskutieren dazu Fehlertoleranzaspekte (Modelle, Consensus, Agreement) sowie Replikationsaspekte (Primary Copy, 2PC, 3PC, Paxos, Quorum-Systeme, verteilter Speicher) und Probleme bei asynchronen Multiprozesssystemen (Shared Memory, Spin Locks, Concurrency). Parallel zur Vorlesung werden einige der Übungen in Form praktischer mehrwöchiger Aufgaben durchgeführt, wobei die Teilnehmer mit der Programmierung von mobilen Plattformen (smartphones) und nachrichtenbasierten Kommunikationsprinzipien vertraut werden. | ||||
